REBOUND conrnon FOR-LASTIHG-MACHINES.

Specification of Letters latent. 1

Application filed December 30; 1910. Serial No. 600,073.

To all whom it may concern Be it known that I, J OSEPH FAossE, a citizenof the United States, residing at Brockton, in the county of Plymouthand State of Massachusetts, have invented certain Im- ".rovemcrts inRebound Control for Lasting-liiachines, of which the followingdescription, in connection with the accompanydrawings, is aspecification, like reference characters on the drawings indicating likeparts in the several figures.

This invention relates to lasting machines and particularly to the typeof bed lasters which is exemplified in United States Letters Patent No.1,018,477, granted Feb. 27, 1912, Brock. Such machines have a slidingcarriage that supports the heel lasting mechanism and which, for eachlasting operation, is moved forwardly from a retracted position in whichit allows the application of the shoe to the machine. In the forwardposition it is retained by a catch during the lasting operation and thenis automatically released. During the lasting operation a spring is putunder compression for closing the heel embracing band and this spring isarranged to force backwardly the heel lasting carriage when the carriageis released, thus opening the machine for the removal of the lastedshoe.

It has been found that in order to serve its purpose in the lastingoperation on the heavier grades of shoes the spring must be of such astrength that the heel lasting carriage is moved backwardly by it withobjectionable force and sometimes it rebounds and comes forward again toa position to obstruct the operator or to cause damage to the shoe.

The object of this invention is to overcome this difliculty.

An important feature of this invention consists in provision forretarding the last portion of the backward movement of the carriage andpreventing objectionable rebounds. In the illustrated embodiment of thisinvention the carriage has yieldingly mounted thereon a finger orprojection and the frame, or a member carried by the frame, has a socketblock to receive the finger as the carriage comes back. In this socketis a spring pressed friction-plug that engages the finger and not onlyretards the final portion of the rearward movement of the carriage butpresses against the finger and prevents the rebound of the carrlage. Thespring mounting for the finger takes up, the slack as the carriage comesback and furnishes enough rebound force to start the finger forwardlyout of engagement with the plug. The friction plug is adjusted in thesocket block to give only sufficient resistance to accomplish thedesired purpose without holding the carriage back to add a load to theoperators work in advancing the heel lasting mechanism for the nextoperation. 1 i

This invention will now be explained in connection with the accompanyingdrawings and will then be pointed out in the claims. Figure .l is a rearside elevation of so much of a machine of the type referred to as isnecessary to a clear understanding of the invention. Fig. 2 shows thesocket block, partly in section.

The heel lasting carriage 2 carrying the usual lasting devices slidesforwardly. and backwardly on the frame 4;, which has a track for theanti-friction rollers 5. In. operation theucarriage is locked in itsforward position by the latch 6 which is fast on a rock shaft 8, thathas an arm 10 which overlies tripper 12 which releases said carriage.

H The machine has a cam 30 which through suitable connections actuates arocker 28 and a leverl25 which is pivoted at 27 and is connected at itsupper end through a spring 24: withthe heel band closing mechanism allas more fully described in said patent. The cam 30 continues to maintainthe spring 24 under tension after the latch 6 is released and thereaction of said spring then causes the lever to fulcrum against therocker 28 and kick the carriage to the left in Fig. 1. On the rear sideof the carriage is mounted yieldingly by spring 14- a rod or finger 18,the finger having a collar 19 against which the spring presses to holdthe finger projected rearwardly. The frame supports by a clamping bolt32a block 35 in which is formed a socket located in alinement with thefinger or rod 18 and of about the same diameter. The block is also boredvertically to form a socket which contains a friction plug 34-, a spring36 and an adjusting screw 40. The plug 34 projects far enough into thefinger socket so as to engage the finger 18 frictionally and the screw40 adjusts the tension of the spring 36.

Patented Oct. 13, 1914.

When the carriage is released by means of the tripper 12, which israised by the cam 38 tolift the latch 6, the heel carriage is forcedtoward the left in Fig. 1 by the contraction of the spring 24:. As thecarriage approaches the limit of its movement the finger18 enters thesocket block 35 and has its movement checked as it slides under thespring pressed plug 346. Then the reaction of the finger spring 1%,which has been compressed as the backward movement of the carriage waschecked, reverses the movement of the heel carriage and presses itforward enough to free or substantially to free the finger 18 from thesocket block so that the carriage comes to rest without objectionableshock or rebound.

Having explained my invention I claim as new and desire to secure byLetters Patent of the United States 1. In a machine of the classdescribed, the combination with a heel lasting carriage and a slidewaytherefor, of means acting to move said carriage along the slideway, afinger on the carriage, a socket block on the slideway formed to receivethe finger, and means for engaging the finger and arresting it bysliding friction While it is in the socket block, the finger and blockbeing constructed and arranged to continue the friction throughout thepossible movement of the finger into the socket block.

2. In a machine of the class described, the combination with a heellasting carriage and means for automatically moving it rearwardly afterthe lasting operation, of a finger projecting rearwardly therefrom, andmeans for slidingly engaging said finger as the carriage approaches theend of said movement and continuing in engagement therewith to the endof the possible rearward movement of the carriage gradually stoppingsuch movement and resisting return movement of the finger to preventrebound of the carriage.

3. In a machine of the class described, the combination with a heellasting carriage and means for automatically moving it rearwardly afterthe lasting operation, of a finger projecting rearwardly therefrom, adevice in contact with said finger slides during the last portion of therearward movement of the carriage and which checks said movement, aspring compressed by the re sistance encountered by said linger andarranged to react to move the carriage forwardly to free the pin fromsaid device.

4. In a machine of the class described, the combination with a heellasting carriage and means for automatically moving it rearwardly afterthe lasting operation, of a finger 28 and a spring 1+1- yieldinglyprojecting the finger from the carriage, a socket block 35 having in itsfront end a socket to receive the finger and a friction plug 36projecting into the socket to engage the finger to resist both rearwardmovement of the finger and then forward movement thereof when the spring14: reacts, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
